Sakuya Ohtori

Sakuya Ohtori serves as both butler and self-appointed elder brother to Chihaya Ohtori, playing a pivotal role throughout the story. While he projects an air of polished sophistication, he shows little warmth toward the protagonist Kotarou, often greeting him with cutting remarks and a cold demeanor. His combat prowess is considered unparalleled within Gaia, earning him the title of the organization's supreme familiar. Beneath this formidable exterior lies a tragic history: Sakuya was once a Rewriter of a previous generation whose relentless use of his abilities gradually transformed him into a monster. Despite this fate, his devotion to Chihaya remains absolute, making him an indispensable force in both battle and support throughout the narrative.
